从MVC应用程序创建模型时出错 [英] got error in creating models from MVC application

问题描述

hi ..

我是mvc 3的初学者

我已经为服务器上的应用程序设置了数据库.
一切都很好...除了

当我创建新记录时，这会出错.

 @ model Surveys.SurveysServiceReference.Survey

@ {
    ViewBag.Title =创建";
} 

它显示SurveysServiceReference上的错误，找不到服务引用.

我有将其弄皱的模型.

使用系统；
使用System.Runtime.Serialization;
使用System.Collections.Generic;

命名空间SurveysService.Models
{
    [DataContract(IsReference = true)]
    公众课调查
    {
        公众调查
        {
            this.Topics =新列表<  主题 > ();
        }
        [DataMember]
        public int SurveyID {放; }
        [DataMember]
        公共字符串Title {get;放; }
        [DataMember]
        公共字符串CreatedBy {get;放; }
        [DataMember]
        public Nullable <   System.DateTime  > 日期{得到；放; }
        [DataMember]
        公共虚拟ICollection <  主题 > 主题{get;放; }
    }
} 

请给我指导在数据库中创建记录.

谢谢

除了给出的答案外，还应该为视图创建视图模型，这些视图模型封装一个或多个模型对象以及该视图特定的其他数据正在创建.

hi..

        public virtual ICollection<Topic> Topics { get; set; }
    }
}

Apart from the answer you were given, you should create viewmodels for your views, these encapsulate one or more model objects and other data that is specific to the view being created.
